Android :: Lines And Drawables Draw Order In Google Maps
Nov 11, 2010
I'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.
One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.
The second extends from Overlay, and in the draw method y draw the line with the method drawline of the canvas.
The problem i've is that the lines are drawn over the ItemizedOverlay items, no matter the order i add them to the mapView.getOverlays().
I want the lines on the bottom of all overlays. is there a way to do that.

Does anyone know how to display points, lines etc. (basically every overlay) created in android in standard google maps on website? The android db is synchronized with remote db. I'm getting the points from the database, creating kml file from them and uploading in to the map. The problem is that the areas I've created are not appearing where they should. They're somewhere on the ocean.
I thought that's because I'm running this code in android:
CODE:...................
So basically I'm doing microdegrees here. I thought that dividing lat and long from db by 1E6 would do the trick but it didn't. Can someone please help me on that one?

what is best way to create app in which I only need to draw simple lines through onTouchEvent? When i use invalidate everytime i draw any line, that erase lines i draw before. But if I use some List structure to store drawed lines it lose performance. Is there any simple way to do it?

I am working on a paint application for Android. Now I want to implement an eraser to allow erasing parts of a loaded bitmap by using touch input and making the bitmap transparent along the finger's path.
A very good example of what I try to achieve is shown in the application Steamy Window for Android. Steamy Window simulates a fogged window, where a user can wipe parts of the fog via touch input.
UPDATE: I have posted the most important sections of my current code below. I am not really happy with it for the following reasons:
Drawing is quite sluggish. What can I improve here?
I am looking for a way to use an alpha mask in order to set the pixel transparency/alpha of the pixels as I want to simulate a paint brush. Any suggestions how this could be achieved?

What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...

I tried enough to find in google & android this question. Also did several trials & errors, but couldn't get this question. was learning Android's "Draw Nine Patch" images. One basic I know is that, whatever image you process must be in .png format (if it's already in .9.png then it will be ignored by tool). However, couldn't understand what it literally means by "stretchable patches" ? what exactly happens when you draw black dots outside the .png image ? (preview pane shows changes happening, but I am unclear on how it makes those)When I draw black dots in left/top sides of image it shows some changes in preview; but why isn't there any effect when you do the same on right/bottom side of the image ? why this tool is used primarily for background, when we try to process on the image itself ?i am trying to modify a simple button.png (given in android sdk). Whenever I use this tool & draw black lines, it reduces the size of the image instead of 'stretching' it! Why ?What is the significance of options given below like, "show lock", "show content", "Patch scale" and so on ?I apologize for asking so many questions, but in Android online docs they haven't explained well for novice. If someone can answer these, it will become ready reference for all the begineers who search this forum.

I am wondering if there is a way to draw an image, or edit simple lines in a text box. The entire screen is a textView/ect and i would like to be able to write a sentence then draw an image and write again. By draw i think i would use the Canvas, so basically is there a way to include a canvas in a text view?
Evernote does do this, but to edit an image/draw you need to open another app "Skitch", my goal is to try and do this without any extra apps.
For example:
Hello
(canvas/editable graphical items)
World

I want to have a elmenent with a 2 color border outline. I can do a single color outline using the element, but this only allows me to draw a single line. I tried using 2 elements within my but that didnt work either. Is there a way to either draw a shape within a shape or draw 2 lines around my shape (which has rounded corners btw).

I'v been busy for a long long long time finding out how to draw a line between two (gps) points on the map in HelloMapView but with no luck.Could anyone please tell me how to do so.Suppose I use the HelloMapView which extends MapView. Do I need to use overlays? If so do I have to override the onDraw() method of the overlay and draw a line here? I actually tried these things but with no result.

I'm not sure how many of you have noticed, but the reporting system of Google Checkout has been broken since around noon on Friday. Orders continue to display in the web interface, but any attempt to query for orders via HTTP requests or exporting orders to .csv files only returns updated information prior to 3/5/10. For example, if you had 50 sales yesterday and tried to access the orders via the notification API or my exporting a spreadsheet, the request would return no information.
I'm not even sure that the Google Checkout team is aware there is a problem. I posted a message in the Google Checkout forum:
http://www.google.com/support/forum/p/checkout-merchants/thread?fid=5...
There has been no official response. I realize it was over the weekend, but it's really starting to have a negative impact. If you are a dev affected by this, please either post in the thread I linked to or try to contact Google. If someone from Google actually reads this, could you please try to make the relevant team aware of this issue if they are not already?

Is Google Latitude available in the UK or not, because it doesn't seem to be working for me? I have received the RC9 update for G1 and have Google Maps 3.0. Is there an a Google Latitude application that I should have or do I access everything through Google Maps? When I go the www.google.com/latitude on my G1, it offers me the option of "launching" Latitude but it just takes me to Google Maps. From there, I cannot see the locations of my Google "friends" (who have agreed to show location), neither does my own location show up on the Latitude homepage on the web (I have settings turned to "detect my location automatically").

As you may know, when you buy an app from the market, an email is sent to you with a "Google order number" (which I believe is 15 digits long), which is specific to this transaction. I was wondering if this number is stored anywhere on your device after you purchase an app, and if it is, is there anything in the API to allow an android app to retrieve this number. If this number cannot be retrieved, is there a similar market transaction code that's retrievable?

I'm using the latest version of Google Maps on JB 4.2.2 [Nexus 4]..I noticed that I cannot edit the names of my locations in "My Places" in the phone app. So I used Google Bookmarks (google.com/bookmarks) from my PC to edit/rename My Places. However, the names do not sync or carry through to the Google Maps app on the phone. The names in the app are still the generic names, coordinates or street names.
Is there any way to change the names of My Places and get them to sync with the phone app? Really baffling!

I was looking at Google's Nexus One order page earlier today and I noticed that Google is actually recommending the EVO for Sprint customers. It makes it seem more and more likely that the EVO will be one of the first phones to get the Froyo update once it's ready for the public.

I ordered password manager for dolphin browser HD2, they pulled back the app refunded my money and said this,"Thank you for using Google Checkout. In an ongoing effort to provide a safe purchasing environment, Google reviews orders on a regular basis.For your security, we've cancelled the following order" "Google Checkout no longer processes orders for this merchant. If you'd still like to make a purchase from Dolphin Browser Add-ons, please contact this merchant directly or feel free to retry your order with another merchant" Has anyone else experienced this? Anyone have a better explanation than the canned response from Google's legal team.

right so the bottom buttons were working fine, but the next day, the back button takes me to the home screen :S so if im on facebook, press the back button, instead of going to the previous page. and i also set up the draw thing to unlock it, but as it was raining a little it said i entered it wrong too many times and asked for the google mail thing... but i really have no rememberence of making one, which is so ******* annyoying.
the only way ive found out to solve this problem is doin a phone software update, however as my bottom right button is working properly, everytime i hold it down to plug the phones usb, the phone just starts normally, so basically i cannot do the system update.
